Description

Technical Field

[0001] This utility model relates to the field of machine tool processing technology, specifically to an automated cutting fluid spraying assembly for machine tool processing. Background Technology

[0002] Cutting fluid spraying is a common cooling and lubrication method used in machining processes. Its main functions include: cooling, effectively reducing the temperature of the cutting area, preventing tool and workpiece deformation and wear due to high temperatures, thereby extending tool life and improving machining accuracy. For example, in high-speed cutting, the heat generated is extremely high, and cutting fluid spraying can quickly remove this heat, ensuring machining stability; lubrication, reducing friction between the tool, workpiece, and chips, lowering cutting forces, and improving surface quality. For instance, when machining materials with high hardness, good lubrication can reduce tool wear and cutting resistance; and chip removal, quickly flushing away chips generated during the cutting process to prevent chip accumulation from affecting normal machining.

[0003] Currently, most cutting fluid spray structures are directly fixed to one side of the cutting tool, and the spray end is directly aimed at the end of the cutting tool to spray in a fixed direction. In this spraying method, the impact on the chips is a continuous impact in one direction, which makes it difficult to flush the chips off, resulting in unsuccessful chip removal.

[0009] Preferably, an arc-shaped guide rod is fixedly provided inside the arc-shaped guide groove, and one end of the arc-shaped guide rod passes through the arc-shaped guide block.

[0010] Preferably, the power mechanism includes a second movable slot at the top of the mounting base, a second movable toothed plate inside the second movable slot, a second reciprocating screw rotatably connected to the second movable slot via a bearing, a third motor fixedly mounted at one end of the mounting base, the output shaft of the third motor fixedly connected to one end of the second reciprocating screw, a transmission slot connecting the arc-shaped guide slot and the second movable slot, a rotating rod rotatably connected to the bottom end of the transmission slot via a bearing, a gear fixedly mounted at the top end of the rotating rod, the second movable toothed plate meshing with the gear, a rack groove on the inner wall of the arc-shaped guide slot, an arc-shaped rack fixedly mounted at the outer end of the arc-shaped guide block, the arc-shaped rack being located inside the rack groove, and the arc-shaped rack meshing with the gear.

[0012] The technical effects and advantages provided by this utility model in the above technical solution are as follows: 1. By combining the swing assembly and the lifting assembly, multi-dimensional automated adjustment of the spray head in terms of vertical height and spray angle is achieved. Specifically: the first motor drives the first movable toothed plate to move up and down via the first reciprocating screw, which in turn drives the semi-circular gear to make the movable tube swing periodically, realizing the automatic swing function of the spray head; the second motor drives the lifting block to move vertically via the threaded rod, realizing precise adjustment of the spray height. This composite motion mechanism enables the cutting fluid to be sprayed onto the machining area from the optimal angle and position, significantly improving cooling efficiency and chip removal effect, and effectively solving the technical problem of "single-direction continuous impact making it difficult to dislodge chips" in the background technology.

[0013] 2. Through the design of the arc-shaped guide mechanism and power mechanism, a wide range of automated adjustment of the overall angle of the spray assembly is achieved. Specifically, the third motor drives the second movable toothed plate to move horizontally via the second reciprocating lead screw, and through the transmission of gears and arc-shaped racks, drives the entire spray support to swing along an arc-shaped trajectory. This planar swing function, combined with the swing of the spray head itself, forms a complex composite motion trajectory, enabling area sweeping spraying of large-sized workpieces or dynamic tracking cooling of moving tools. This design significantly expands the spray coverage area, improves the efficiency of cutting fluid utilization, and meets the needs of modern machine tool automation and flexible machining.

[0014] 3. The innovative sealed bearing connection structure solves the sealing technology problem of the moving spray system. The spray fluid inlet pipe is connected to the rotating shaft and the moving pipe with a double-sealed bearing, ensuring that the cutting fluid supply system maintains reliable sealing during the multi-degree-of-freedom movement of the spray head, eliminating leakage and improving the system's operational reliability.

[0015] 4. The multi-stage guiding mechanism design ensures the stability and precision of each moving component. Multiple guiding measures, such as the cooperation between the arc-shaped guide rod and the arc-shaped guide groove, and the cooperation between the T-shaped guide block and the T-shaped guide groove, effectively prevent jamming and deviation during movement, ensuring the long-term stability and service life of the spray assembly.

Detailed Implementation

[0019] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0020] Example 1: like Figure 1-5 As shown, the present invention provides an automated cutting fluid spraying assembly for machine tool processing, including a mounting base 1 and a U-shaped nozzle support 5.

[0021] The mounting base 1 is fixedly installed on a suitable position on the machine tool worktable or frame by bolts, preferably close to the processing area but without interfering with the normal movement of the machine tool. The top of the mounting base 1 is provided with a vertical plate 2, and the top of the mounting base 1 is also provided with an arc-shaped guide groove 3. An arc-shaped guide block 4 is slidably arranged inside the arc-shaped guide groove 3, and the top of the arc-shaped guide block 4 is fixedly connected to the bottom of the vertical plate 2 by bolts.

[0022] The specific implementation method is as follows: During installation, firstly, select a suitable installation position according to the specific structure of the machine tool, and then firmly fix the mounting base 1 to the rigid structural component of the machine tool with bolts. The cooperative design of the arc-shaped guide groove 3 and the arc-shaped guide block 4 allows the vertical plate 2 to swing along a stable arc trajectory, providing a basis for subsequent adjustment of the spray angle.

[0023] The U-shaped nozzle support 5 is located on one side of the vertical plate 2, and a lifting assembly is provided between the U-shaped nozzle support 5 and the vertical plate 2. A movable tube 6 is rotatably connected to the inside of the U-shaped nozzle support 5 via bearings. A spray head 7, communicating with the inside of the movable tube 6, is fixedly installed on one side of the movable tube 6. Rotating shafts 8 are fixedly installed at both ends of the movable tube 6, and the two rotating shafts 8 are respectively connected to the inner side walls of the U-shaped nozzle support 5 via rolling bearings.

[0024] The specific implementation method is as follows: the U-shaped nozzle support 5 serves as the mounting platform for the core component, and its U-shaped structure provides ample space for the swing of the movable pipe 6. The movable pipe 6 is rotatably connected via the rotating shaft 8, ensuring that the spray head 7 can flexibly adjust its direction.

[0025] Example 2: Based on Example 1, such as Figure 4 As shown, one end of one of the rotating shafts 8 is connected to a spray fluid inlet pipe 9. One end of the spray fluid inlet pipe 9 passes sequentially through the ends of the rotating shaft 8 and the movable pipe 6, and communicates with the interior of the movable pipe 6. The spray fluid inlet pipe 9 is rotatably connected to the rotating shaft 8 and to the end of the movable pipe 6 via sealed bearings. The other end of the spray fluid inlet pipe 9 is connected to an external cutting fluid storage and delivery device via a high-pressure hose.

[0026] The specific implementation method is as follows: the cutting fluid is delivered from an external supply system through a high-pressure hose to the spray fluid inlet pipe 9, and then through the movable pipe 6 before finally being sprayed out from the spray head 7. The use of a sealed bearing ensures that the cutting fluid supply system remains sealed during the oscillation of the movable pipe 6, preventing leakage. This structural design solves the technical problem that traditional fixed spray pipes cannot adapt to angle adjustments.

[0027] Example 3: Based on Example 1, such as Figure 4 and Figure 5 As shown, the swing assembly includes a first movable groove 10 formed on the inner wall of the U-shaped nozzle support 5, and a first movable toothed plate 11 is slidably disposed inside the first movable groove 10. A semi-circular gear 12 is fixedly installed at the outer end of the other side of the movable tube 6, and the first movable toothed plate 11 meshes with the semi-circular gear 12. A U-shaped plate 13 is fixedly installed at both the top and bottom ends of the U-shaped nozzle support 5 by bolts, and a first reciprocating screw 14 is rotatably connected between the two U-shaped plates 13 by bearings. The first reciprocating screw 14 passes through the first movable toothed plate 11 and is threadedly connected to it. A first motor 15 is fixedly installed at the top of the top U-shaped plate 13 by bolts, and the top of the first reciprocating screw 14 passes through the U-shaped plate 13 and is fixedly connected to the output shaft of the first motor 15 by a coupling.

[0028] The specific implementation method is as follows: When it is necessary for the spray head 7 to swing, the first motor 15 is started, driving the first reciprocating screw 14 to rotate. Since the first movable toothed plate 11 is confined within the first movable groove 10 and can only move up and down, it performs up-and-down reciprocating motion under the drive of the first reciprocating screw 14. The first movable toothed plate 11 drives the semi-circular gear 12 to rotate reciprocally through tooth meshing, thereby driving the movable tube 6 and the spray head 7 on it to swing periodically within a certain angle range. This swinging spraying method allows the cutting fluid to impact the tool and machining area from different angles, significantly improving chip removal efficiency and cooling effect.

[0029] Example 4: Based on Example 1, such as Figure 3 As shown, the lifting assembly includes a lifting groove 16 formed on one side of the vertical plate 2, and a lifting block 17 is slidably disposed inside the lifting groove 16. The lifting block 17 is fixedly connected to the end of the U-shaped nozzle support 5 by bolts. A threaded rod 18 is rotatably connected to the lifting groove 16 through a bearing, and the threaded rod 18 passes through the lifting block 17 and is threadedly connected to it. A second motor 19 is fixedly installed at the top of the vertical plate 2 by bolts, and the output shaft of the second motor 19 is fixedly connected to the top of the threaded rod 18 through a coupling.

[0030] The specific implementation method is as follows: When it is necessary to adjust the spray height, the second motor 19 is started, driving the threaded rod 18 to rotate. The lifting block 17, which is threadedly engaged with the threaded rod 18, moves vertically under the constraint of the lifting groove 16, thereby driving the entire U-shaped nozzle support 5 and the spray head 7 to rise and fall. This design allows the spray assembly to adapt to processing requirements at different heights, greatly enhancing the adaptability of the equipment.

[0031] Example 5: Based on Example 1, such as Figure 2 As shown, an arc-shaped guide rod 20 is fixedly installed inside the arc-shaped guide groove 3. The arc-shaped guide rod 20 passes through the arc-shaped guide block 4 and slides with it. This dual-guide structure effectively improves the stability and accuracy of the vertical plate 2 during the swinging process.

[0032] Example 6: Based on Example 1, such as Figure 2 As shown, the power mechanism includes a second movable groove 21 formed at the top of the mounting base 1, and a second movable toothed plate 22 is slidably disposed inside the second movable groove 21. A second reciprocating lead screw 23 is rotatably connected inside the second movable groove 21 via a bearing. A third motor 24 is fixedly mounted on one end of the mounting base 1 by bolts, and the output shaft of the third motor 24 is fixedly connected to one end of the second reciprocating lead screw 23 via a coupling.

[0033] A connecting transmission groove is formed between the arc-shaped guide groove 3 and the second movable groove 21. A rotating rod 25 is rotatably connected to the bottom of the transmission groove via a bearing, and a gear 26 is fixedly mounted on the top of the rotating rod 25. The second movable toothed plate 22 meshes with the gear 26. A rack groove 27 is formed on the inner wall of the arc-shaped guide groove 3, and an arc-shaped rack 28 is fixedly mounted on the outer end of the arc-shaped guide block 4. The arc-shaped rack 28 is disposed inside the rack groove 27 and meshes with the gear 26.

[0034] The specific implementation method is as follows: When it is necessary to adjust the overall angle of the spray assembly, the third motor 24 is started, driving the second reciprocating screw 23 to rotate, which in turn drives the second movable toothed plate 22 to move horizontally back and forth. The second movable toothed plate 22, through the transmission of gear 26 and arc-shaped rack 28, converts the horizontal movement into the arc-shaped oscillation of the arc-shaped guide block 4, thereby achieving automated adjustment of the overall angle of the spray assembly. This design allows for a wide range of spray direction adjustments, adapting to complex processing conditions, and can be combined with small-range arc-shaped cyclical movement of the up-and-down swing motion, thus improving chip removal.

[0035] Example 7: Based on Example 6, such as Figure 2 As shown, a T-shaped guide groove 29 is provided on the inner wall of the second movable groove 21, and a T-shaped guide block 30 is fixedly provided on the side of the second movable toothed plate 22 away from the gear 26. The T-shaped guide block 30 is disposed inside the T-shaped guide groove 29. This T-shaped guide structure ensures the smoothness and directional accuracy of the movement of the second movable toothed plate 22, and prevents the toothed plate from deviating or jamming during movement.

[0036] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
